Medical and nursing staff working in hospitals often experience exposure to extreme sound environments, and there is growing evidence of the negative impacts. Previous research highlighted various complexities regarding noise sources in hospitals; however, identifications of intrinsic noise categories that can reveal the complex mixture of existing hospital noise is still limited. The objective of this work was to identify intrinsic categories of the noise sources based on staff perceived annoyance and explore clear associations of these categorized noise sources with psychological perceptions. The staff perceptual responses regarding hospital noise were assessed by conducting surveys at the three pediatric and neonatal care units in two hospitals. Using principle component analysis (PCA), the psychological annoyance responses of 94 participants were used to derive the inherent structural patterns of the existing noise sources. The derived PCA categorization was validated on mixed-model analysis of variances, and employed on regression models to explore potential associations between the categorized noise factors and the staff's psychological perceptions. The results highlighted three intrinsic noise categories and their negative impacts on staff's psychological perceptions including work/rest disturbance and noisiness. Taken as a whole, the findings better reveal problematic noise source categories and establish a framework for hospital noise control that is less source-specific and more broadly generalizable.

This retrospective, exploratory study examined 8,366 patient responses to surveys on patient satisfaction and patient room spatial layout in a large academic teaching hospital consisting of 17 nursing units and 382 patient rooms. This study included four spatial measures: average distance to the nurse station, room handedness, location of bed, and location of first encounter-and explored their statistical associations with two types of patient satisfaction surveys (Hospital Consumer Assessment of the Healthcare Provider and Systems and third party). The study had two phases: a preliminary study of 3,751 patient respondents in a limited diagnosis-related group (DRG) over 5 years and a general study of 4,615 patient respondents with a broader range of DRG's over 2 different years from the preliminary study. Findings indicated statistically significant relationships between all four spatial layout measures and specific survey questions pertaining to perception of nursing, physician, individual care, and overall room environment. Results emphasize the importance of hospital design-and spatial layout in particular-on patient satisfaction.

Patient's perception of care-referred to as patient satisfaction-is of great interest in the healthcare industry, as it becomes more directly tied to the revenue of the health system providers. The perception of care has now become important in addition to the actual health outcome of the patient. The known influencers for the patient perception of care are the patient's own characteristics as well as the quality of service received. In patient surveys, the physical environment is noted as important for being clean and quiet but is not considered a critical part of patient satisfaction or other health outcomes. Patient perception of care is currently measured as patient satisfaction, a systematic collection of perceptions of social interactions from an individual person as well as their interaction with the environment. This exploration of the literature intends to explore the rigorous, statistically tested research conducted that has a spatial predictor variable and a health or behavior outcome, with the intent to begin to further test the relationships of these variables in the future studies. This literature review uses the patient satisfaction framework of components of influence and identifies at least 10 known spatial environmental variables that have been shown to have a direct connection to the health and behavior outcome of a patient. The results show that there are certain features of the spatial layout and environmental design in hospital or work settings that influence outcomes and should be noted in the future research., (© The Author(s) 2016.)

Objective: This study investigates the perception of nurses about their lighting environment at medical-surgical hospital units in order to understand areas of improvement for lighting at these units., Background: The bulk of the research about nurses and lighting is focused on nighttime nursing, exploring the disruptions of nurses' circadian rhythm and maintaining alertness. The understanding of nurses' perception about lighting and its impact on nurses' task performance and patient examination remains imprecise., Methods: This study used an online survey to ask a set of questions about lighting in medical-surgical units at five key locations including centralized nurse stations, decentralized nurse stations (DCNS), patient bedsides, patient bathrooms, and corridors from 393 survey participants. It then explored the survey findings in more depth through conducting focus groups with eight volunteer nurses., Results: Lighting conditions at patient besides and DCNSs were significantly less desirable for nurses compared to other locations. A significant relationship between nurses' access to lighting controls (switches and dimmers) and satisfaction about the lighting environment was found. No significant relationship was observed between the individual characteristics of nurses (such as age, years of experience, etc.) and findings of this study., Conclusions: Thoughtful design of the lighting environment can improve nurses' satisfaction and perception about their working environment., (© The Author(s) 2015.)
